The Refractory Reaction Bonded Silicon Carbide Ceramic (RBSIC or SiSiC) Crossbeams have higher bearing capacity with long service life. They are mainly used for the loading structure systems of tunnel kilns, shuttle kilns and many other industrial kilns. The beams are the most suitable kiln furniture for sanitary ceramics and electrical ceramics. The excellent thermal conductivity makes it available to save energy consumption significantly without increasing the weight of kiln cars.
